Whispering gallery mode optical microresonators: fundamentals and applications

Whispering Gallery mode micro-resonators have been widely applied in laser, bio-sensor and quantum physics experiments. This review will give an introduction to the basic properties and principles of those cavities. Also, the coupling with outer light is present. Based on recent worldwide progresses and research in University of Science and Technology of China, we introduced the detailed applications in modern scientific research with Whispering Gallery mode micro-resonators.
